	Presumably there is a Macos driver that sets up the environment
	such that the DOS or Win95 can run OK. If you can get something
	in NetBSD to do the same then it should be possible to run DOS
	or Win95 on the card.

	As for running NetBSD on it... hmm - the 'simple' option might
	be to write a psuedo network interface that communicates with
	other CPUs using shared memory (and whatever type of interlock
	is provided), and then run the card as a diskless NetBSD/i386
	system with only that device driver (no disk, keyboard, video
	etc). The more adventurous could add in disk drivers etc (as long
	as the different cpus used different areas of the disks :)

	Nice project for someone with the time!
